GAL Assessment Units 1000m 20160522 v01

Abstract

The dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets. You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.

To ensure efficiency for processing speed and rendering this is a clip of the Vector Reference grid for the GAL region.

It was created with a 50km buffer of the extent of the Hunter PAE and then selecting all grid cells that intersect with the extent.

The unique ID field for each grid cell is AUID and starts from 1 in the reference grid. The grid also has a column id and row for easy reference

The grid is in Australia Albers (GDA94) (EPSG 3577)

Purpose

This is an attempt to standardise (where possible) outputs of models from BA assessments and is the template to be used for GAL (clipped from whole of BA reference Grid) for the groundwater and potentially surface water model outputs.

Dataset History

The minimum bounding geometry tool in ArcGIS 10.1 was used to return the extent of the Bioregion boundary. This was then buffered with a 50km radius.

The select location tool in ArcGIS 10.1 was then used to select all gridcells within the buffered extent.

An export of the grid cells was then created to produce a rectangle reference grid of the GAL region.

The file contains 2 shape files

1) The grid cells clipped to the boundary

2) The boundary extents as a reference of the Region
